Version-Release number of selected component (if applicable): vmlinuz-2.6.9-67.0.4.ELsmp How reproducible: Didn't try Steps to Reproduce: 1. reboot machine Actual Results: It froze up Expected Results: It should have rebooted Additional info:
dbyrne, we need a little bit more information -- can this issue be reproduced? Also, did this happen while the system was idle, or during boot-up/reboot?
I see [nvidia] in that backtrace, and a tainted kernel... and the process was grep. Any idea what was being grepped at the time?

No, the machine was simply rebooting after a power failure, so it was not a user-level grep. I have not tried manually rebooting to see if it is reproducible, but I can if necessary.
dbyrne, could you attach the console log output to this BZ? Thanks, P.
